Introduction3:17
Explore piping material specification (PMS) as the master document guiding pipes, valves, fittings, flanges, gaskets, moc ratings, prepared jointly with process and instrumentation engineers for EPC.
PMS-Reference documents, drawings and standards7:10
Identify and reference key drawings, documents, and standards for PMS generation, including ASME B31.3, ASME section II materials, API and ISO piping standards, and PFD/P&ID guidance.
PMS Generation-Activity sequence4:00
Master the PMS generation activity sequence, including pipeline and service fluid identifiers, material standards, and PMS tables for flanges, fittings, gaskets, fasteners, and valves.
Identify material standards4:44
Identify material standards for piping using ASME section II, part D, based on maximum operating temperature; engineers select carbon steel, stainless steel, alloy steel, and non-ferrous materials per the PMS.
Flange Pressure Rating5:02
Learn to fix flange pressure ratings from ASME II part D tables, select A182 grade F316, and finalize ASME B16.5 working pressures using a PMS index and piping spec identifiers.
Branch Connection Standards5:46
Explore branch connection standards in PMS, including preparing a branch connection chart, selecting ASME B16.9/B16.11 and B30 code compliant fittings, and addressing header weakening with approved branch connections or pads.
PMS Chart and Conclusion8:15
Prepare the PMS chart and document for pipes, flanges, fittings, and valves, detailing ASME B31.3 code, service, temperatures, pressures, materials, corrosion allowance, nominal bore, schedule rating, and spec numbers.

Requirements

Basic knowledge of various pipes and fittings used in process industry

Description

Piping Material Specification(PMS) is one of the most critical document to be generated by the mechanical engineer carrying out EPC of chemical projects. This document has to be prepared jointly with process engineer when developing the P&ID since these details are required for pipe line numbering and is referred to by all stake holders and in particular by the instrumentation engineer who is involved in generation of P&ID.

PMS is the master document for finalizing the specification for pipes, valves, fittings, flanges, gaskets and fasteners and also for selection of MOC , rating and end connections of field instruments like control / safety valves, flow meters, transmitters etc. Hence, this document has to be generated diligently to ensure accuracy as this impacts the procurement process and has cost implications. This document is essential for input in the Legends & Symbols sheet created for the project.

This course gives a step by step approach for generation of this critical document, the codes and standards to be referred and gives samples of detailed templates to be prepared. Preparation of this document is done in consultation with Process engineer or Process consultant. An accurate PMS is a must for all projects since this impacts the procurement as the inter connection with piping and instrumentation is involved and has to be coordinated to ensure proper installation of all instruments.

Who this course is for:

Fresh mechanical / Piping engineers in EPC companies executing chemical projects
